##### Method of solving this CAT Question from Line Graphs: Lengthy calculations!

For this we need to fill in the grid completely and then find overall revenues. Thankfully, we have already computed for 2 different years. (For previous questions). We need to compute only for 2009 and 2015.

With this, we can complete the overall grid. The overall grid should make the last question also simpler.

The maximum year on year growth rate was seen in 2009.

We could have obtained this by scanning at the growth rate graph as well. The Pharma number is off the charts and all 4 growth rates are positive. The 21% growth rate in Technology is also pretty high. So, here was an easy question that we have gone about in a roundabout fashion.

The question is "Which year saw the highest percentage growth in revenues overall?"

##### Hence, the answer is "2009".
